CVE-2016-6830
CRITICAL9.8EPSS 0.55%chicken - security update
Published: 1/10/2017Modified: 4/28/2026
Description
The "process-execute" and "process-spawn" procedures in CHICKEN Scheme used fixed-size buffers for holding the arguments and environment variables to use in its execve() call. This would allow user-supplied argument/environment variable lists to trigger a buffer overrun. This affects all releases of CHICKEN up to and including 4.11 (it will be fixed in 4.12 and 5.0, which are not yet released).
Affected packages (2)
- Debian/chickenfrom 0, < 4.12.0-0.2
- Debian/chickenfrom 0, < 4.7.0-1+deb7u1
